Tytuł:: StegHash : New Method for Information Hiding in Open Social Networks
Autorzy:: Szczypiorski, K.
Powiązania:: https://bibliotekanauki.pl/articles/226661.pdf
Data publikacji:: 2016
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: information hiding

StegHash
Opis:: In this paper a new method for information hiding in open social networks is introduced. The method, called StegHash, is based on the use of hashtags in various open social networks to connect multimedia files (like images, movies, songs) with embedded hidden messages. The evaluation of the system was performed on two social media services (Twitter and Instagram) with a simple environment as a proof of concept. The experiments proved that the initial idea was correct, thus the proposed system could create a completely new area of threats in social networks.

Opis:: This article presents a new method for detecting a source point of time based network steganography - MoveSteg. A steganography carrier could be an example of multimedia stream made with packets. These packets are then delayed intentionally to send hidden information using time based steganography methods. The presented analysis describes a method that allows finding the source of steganography stream in network that is under our management.

Powiązania:: https://bibliotekanauki.pl/articles/226114.pdf
Data publikacji:: 2016
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: training steganography

cluster systems
parallel staganography
Opis:: This paper summarizes the experience and the learning outcomes of students of the "Informatics" specialty at the Episkop Konstantin Preslavsky University of Shumen (Bulgaria) on the problems of computer and network security as a component of their professional training. It is a continuous process starting from the "Computer steganography" course and turning into diploma papers, masters programs, specializations and PhDs in computer and network steganography. The outcome of this training would be bachelors and masters theses, practical activities of experimentation of stego software and steganology in a parallel computing environment, joint scientific publications of lecturers and students.

Tematy:: hash function

Shrinking decimation rule
Pseudorandom number generator
Opis:: We present a new hash function based on irregularly decimated chaotic map, in this article. The hash algorithm called SHAH is based on two Tinkerbell maps filtered with irregular decimation rule. We evaluated the novel function using distribution analysis, sensitivity analysis, static analysis of diffusion, static analysis of confusion, and collision analysis. The experimental data show that SHAH satisfied valuable level of computer security.

Opis:: In this study, we propose a novel keyed hash algorithm based on a Boolean function and chaotic attractor. The hash algorithm called BentSign is based on two Signature attractors and XOR function and a bent Boolean function. The provided theoretical and experimental results confirm that the novel scheme can generate output hashes with a good level of security, collision resistance, and protection against most common attacks.
